Important Podcast Question

Dear Apple Podcast Community,

We have a very particular problem that our developers just don't have experience to deal with.

We currently publish 3 podcasts in itunes:

We publish the podcast posts on our website and that feed is connected to FEEDBURNER. iTunes grabs the feedburner link and publishes our podcast.

My problem is this:

We're doing a website redesign and our original (onsite) url might change. So, given that, IF we connect the new urls for each podcast into feedburner respectivelly BUT feedburner URL remains the SAME. Will that affect itunes anyhow?
